T-Mobile, Vodafone and KPN raided in Dutch price-fixing probe

Details are pretty slim at the moment, but it appears that Vodafone, KPN and T-Mobile are among the companies that have been raided by Dutch regulators in a price-fixing investigation. The country's competition authorities, NMa, swept through the carriers' offices as part of a probe into alleged "cartel agreements" exposed by whistleblowers. All three of the companies have agreed to cooperate with the investigation and have denied wrong doing but, they're starting with a dark cloud of suspicion hanging over their heads already. It was only ten years ago that the same three mobile operators were fined for illegally coordinating on pricing and fees. Obviously, it's wrong to jump to conclusions, but what are the chances these huge corporations just haven't learned from their past mistakes?
